Update: (please download plugin at first post)
Add expression:Date2UnixTimestamp(year, month, day, hours, minutes, seconds, milliseconds) to convert date into timestamp.
Add optional second parameter into expression:Year(timestamp), expression:Month(timestamp), expression:Date(timestamp), expression:Day(timestamp), expression:Hours(timestamp), expression:Minutes(timestamp), expression:Seconds(timestamp), expression:Milliseconds(timestamp) , to convert timestamp into date.
So that user could transfer timestamp from/to date.
